For the wear-resistant layer welded on stainless steel surfaces, if a hardness of over HRC60 is required, it is generally recommended to use D707 welding rods. The D707 electrode is a highly alloyed iron-based electrode that possesses excellent wear resistance and high hardness, making it suitable for working environments where high wear resistance is required. The D246 electrode is a medium-alloy iron-based electrode with relatively low hardness, suitable for some ordinary surfacing tasks. Therefore, as required, choosing the D707 electrode is more appropriate. .
